OEM Carrier Defrost Control Board HK32EA001 for Model PH15NB04200GBBAA

This is the genuine OEM Carrier defrost control board (part number HK32EA001), factory-specified for the Carrier PH15NB04200GBBAA heat pump. The defrost control board monitors outdoor coil conditions and initiates timed defrost cycles to prevent ice buildup on the evaporator coil. When this board fails, the heat pump may run continuously in defrost mode, never enter defrost at all, or lock out entirely — resulting in a frozen outdoor coil, reduced heating capacity, and potential compressor damage if left unaddressed.

• Specs: OEM Part No. HK32EA001 | Also cross-references CEPL130524-01, CEBD430524-06A, 151922 | Selectable defrost intervals: 30 / 60 / 90 minutes | 24V control circuit | Factory-authorized replacement for Carrier, Bryant, and Payne heat pumps
• OEM vs Generic: This is a genuine Carrier factory-authorized board — not an aftermarket substitute. OEM boards are built to exact tolerances, preserve published system efficiency ratings, and carry full factory support. Aftermarket boards may use off-spec timing components that cause erratic defrost cycles and accelerated compressor wear.
• Install difficulty: 3/5 — Requires disconnecting 24V control wiring and low-voltage connectors. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter (to confirm 24V supply), and phone or camera to photograph connector positions before removal. Always cut power at the disconnect before accessing the control board.
• Warranty & Shipping: 1-year OEM factory warranty against defects. In stock — ships same business day from our warehouse.
